Description

High-strength high-elasticity pressure gauge spring tube

Technical Field

The utility model relates to the technical field of spring tubes, in particular to a high-strength high-elasticity pressure gauge spring tube.

Background

The spring tube is also called a Bowden tube, and is an elastic sensitive element for measuring pressure by utilizing bending change or torsional deformation of the tube, one end of the spring tube is fixed, the other end of the spring tube is movable, the cross section of the spring tube is elliptical or flat, the tube with a non-circular cross section gradually expands into a circular shape under the action of the internal pressure of the tube, and at the moment, the movable end generates displacement with a certain relation with the pressure; the movable end drives the pointer to indicate the pressure. The most commonly used bourdon tube is of the C-type, and in addition, there are spiral, C-type combinations, and the like. The spring tube is made of copper-based or iron-based alloy, is commonly used for measuring larger pressure, and is often used in combination with other elastic elements.

In the actual use process of the spring tube, the deformation degree of the fixed end is large, and the damaged fixed end of the spring tube is usually the fixed end of the spring tube, so that the precision of the spring tube is mainly influenced by the fixed end of the spring tube.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides a high-strength high-elasticity pressure gauge spring tube.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a high strength high elasticity manometer spring pipe, includes the spring pipe, the spring is equipped with to the outside cover of the link of spring pipe and fixing base, the lateral part of spring pipe is provided with the strengthening rib.

Further, at least one of the inner circular side and the outer circular side of the spring tube is provided with a reinforcing rib.
